The AWSM module provides a receptacle for the stencil, where it is clamped in the correct position
for printing. The module width can be easily adjusted to accommodate stencils from 29 inches
through to 12 inches square with 250mm belt support plates, or 29 inches through to 23 inches
square with 500mm belt support plates.
NOTE
The height of the stencil must exceed 19mm to be clamped firmly.
The stencil image can be front or centre justified.

The pneumatic push buttons located on the inside of the front left and right hand web assemblies
are operated, releasing all four web assemblies on the front and rear rail assembly guide shafts.
Releasing the web assemblies allows the user to adjust the position of the left and right hand chase
rail assemblies, to accommodate for the appropriate size stencil using the stencil width measuring
scale.

The stencil is loaded from the front of the printer and slid into the printer along the top of stencil
support plates. Three stencil location leaf springs (located in the right hand chase rail assembly)
ensures the stencil is pushed against the stencil guide strips on the left hand chase rail assembly.
The stencil is clamped in the AWSM using pneumatically activated flaps that clamp the stencil to
the stencil support plates.
The AWSM is a floating assembly mounted on a bearing set and is aligned to the correct printing
position using three actuators. Once aligned, the AWSM is pneumatically clamped to the left and
right printhead assemblies (for further details refer to 14 "SCREEN ALIGNMENT MOD-
ULE" [}185]).
